Hygroscopic, breathable and antibacterial ultra-high molecular weight polyethylene blended core spun yarn and production method thereof

The invention relates to a hygroscopic, breathable and antibacterial ultra-high molecular weight polyethylene blended core spun yarn and a production method thereof. The yarn consists of a core yarn and a cladding yarn, wherein the core yarn is an ultra-high molecular weight polyethylene filament double-twisted yarn; the cladding yarn is a blended yarn consisting of the following three components: 55 to 65 percent of bamboo fiber, 25 to 30 percent of long lint cotton and 10 to 15 percent of terylene; the weight of the cladding yarn is 1.5 to 2 times that of the core yarn. A process for producing the yarn comprises the following steps of blending the bamboo fiber and the terylene fiber, and manufacturing the bamboo fiber and the terylene fiber into a first cotton roll; manufacturing the long lint into a second cotton roll; manufacturing the first cotton roll into card slivers; manufacturing the second cotton roll into combing slivers; manufacturing the first card slivers and the combing slivers into drawing slivers through three drawing procedures, manufacturing drawing slivers into roving; double-twisting ultra-high molecular weight polyethylene filaments into a double-twisting yarn; taking the roving as the cladding fibers, taking the double-twisting yarn as the core yarn, and manufacturing the roving and the double-twisting yarn into the blended core spun yarn. The advantages of high strength, high modulus and good protecting performance of the core yarn, the advantages of moisture absorption, breathability, bacterium resistance and ultraviolet radiation resistance of the bamboo fiber, the characteristic of comfort of the cotton and the characteristic of stiff and neat property of the terylene are combined, so that the quality of the finished yarn is better.
